Two Dimension Frequency Scanning Antenna

Abstract

In this paper, a high-frequency frequency scanning antenna based on metasurface is designed. The antenna proposed here consists of three parts: an 1 × 16 unequal divider, 16 BJ900 waveguides and 160 metasurface. The proposed antenna is fed by a standard waveguide BJ900 with periodic metasurface covered on it. The working band is 76–81 GHz. To realize two-dimension beam scanning, an unequal divider is designed. After the final optimization, we can get from the simulation results that the working angle is 30° in both two dimension and the radiation efficiency can reach -0.1 dB. The total realized gain of the antenna can reach 20 dB.
